At first, you will need about one square foot of thin copper plate, two alligator clips and short leads of wire, a wide mouth glass jar, tap water and salt. Cheers,

Q:how do buildings circulate energy?

The answer depends upon the type of solar energy captured . Photovoltaic Solar Panels convert the energy into electricity. This electricity is ran throughout the building via wires. Thermal Solar Panels typically capture the energy in the form of heat. The hot water is circulated through the building in water pipes.

Q:Which spectrum of sunlight generates the electricity in a solar panel?

I think it's in the Ultra-Violet range because Solar Panels will still put out almost full power on an overcast day.

Q:Amount of solar panels needed to run a/c and pool pump?

Solar panels are not going to be able to run a pool pump 24/7. They will only produce their rated electricity for 4 to 8 hours a day. For the balance you will need a grid connection or a battery backup. Running the AC would require different power levels depending upon humidity, outside temperature levels, solar gain for the house, and insulation levels. An underground house in Maine will be much easier to AC than a Glass house in Arizona. First find the power requirements. If you had the existing equipment they will have a label with the power requirements or the minimum breaker required if nothing else. For example the pool pump may require a 0 amp 240 breaker while the AC may require a 30 amp 240 breaker. That would be 2400 watts for the pump and (30 x 240) 7200 watts for the AC or a total of 9.6kW each hour of operation. (max) You will next need to find the rated capacity of the solar panels. If each panel were rated at 300 watts then you would need 32 panels for the daytime use and perhaps more to fill in a battery backup. All the numbers are very rough estimates.

Q:would the planet cool if covered in solar panels?

No, the top argument is that extra CO2 is inflicting the ambience to keep greater warmth from the sunlight. Having image voltaic panels might scale returned the quantity of CO2 interior the ambience we are putting in it real now via giving us an means source that doesn't emit CO2, and that's approximately it.

Q:help setting up a solar panel system?

if the cabin is in the woods it is unlikely to get enough sun to power solar panels 45 watts will not even power a light bulb and although it will trickle charge a battery it will not charge then enough over daytime for much else, most tools are a minimum of 550 watts, you really need to be in arizona for solar power to contribute effective wattage

Q:Solar panel Efficiency in Tropics?

0 kWh

Q:Solar panels require big initial investment, how can I check if the money I save will be more than that?

Your school spend $0,000 per month or per year?? Photovoltaic (Solar Panel) panels have a really large initial capital investment. If you live in a location (e.g. West Coast Desert, SoCal) where there are many sunny days so you might be able to break even quicker. Also note ,there are state and federal grants that can help ease the capital cost. Energy demand keeps going up so expect our current rates to double. People who have alternative forms like wind and solar will have the advantage when this time comes. Just think of when the US had it's oil crisis in summer of 2008, people with small efficient vehicles such as Prius's didn't feel the price increase like the people who bought cheaper large SUV's.

Q:Do solar panels generate power when it's cloudy?

Yes. If there is any light, even on a cloudy day, a solar panel can generate power. But the amount of power generated is much less when the solar panel is not in direct sunlight (about 90% less). On a cloudy day, typical solar panels can produce 0-25% of their rated capacity. The exact amount will vary depending on the density of the clouds, and may also vary by the type of solar panel; some kinds of panels are better at receiving diffuse light. SunPower solar cells, for example, have been designed to capture a broader range of the solar spectrum. By capturing more red and blue wavelengths, their solar panels can generate more electricity even when it’s overcast. Ultraviolet light also reaches the earth’s surface in abundance during cloudy days (if you’ve ever been at the beach when it’s cloudy and gotten a sunburn, you’ve experienced this firsthand). Some solar cells are in development that can capture UV rays, although these are not out on the market yet. Even with a standard solar panel on a cloudy day, though, you will be able to generate some power when it’s daylight. The same thing is true in foggy weather. If you live in a city with frequent fog, like San Francisco, you’ll still be able to generate electricity when the fog rolls in. :)

Q:Solar Panel Help Please!?

I will give you the tools to answer your own question. Here is the solar resource map: rredc.nrel.gov/solar/old_data/nsr... Use it to look up the hours of peak equivalent sunlight per day in your area. For example, let's say it's 5 hours / day. Then per year you get 365 x 5 = 825 hours of sun Your panel is 20 watts, or 0.2 kW So the energy produced per year is 825 x .2 = 383 kWh You'll have to use the proper numbers for your own area, of course. Anyway, you can take that 383 kWh and determine how much it would cost at local electric rates. Never know, on some islands, it's $.00 per kWh. Check with your local electric company for rates.
